[0031] Example 1

[0032] like Figure 1-5 As shown, the present invention proposes a cable bending device, which includes a mounting frame 1, a conveying roller 2, a rotating assembly and a driving assembly;

[0033] The conveyor roller 2 is rotatably mounted on the top of the mounting frame 1. Above the conveyor roller 2 is a pressure roller 3 for rolling and pressing the cable conveyed on the conveyor roller 2 during use. One end of the mounting frame 1 may be equipped with a blocking structure or a clamping structure (illustrated only in the figure) to prevent the other end of the cable from moving upward when one end of the cable is bent downward, thus preventing the bending operation from being performed. The conveyor roller 2 and the pressure roller 3 may be rollers with grooves or rollers with flat surfaces (illustrated only in the figure).

[0034] The drive assembly is located at both ends of the mounting frame 1 and connected to the pressure roller 3. The top of the drive assembly is provided with a mounting component for mounting the pressure roller 3 on the side of the conveyor roller 2 in use.

[0035] The rotating component is located at one end of the drive component and connected to the conveyor roller 2. It is used to drive the conveyor roller 2 to rotate during use, so that the conveyor roller 2 cooperates with the pressure roller 3 to convey the cable between them, thereby placing the bending point between the conveyor roller 2 and the pressure roller 3, improving the convenience of bending the cable.

[0036] In this embodiment, the pressure roller 3 is installed at a distance from the conveyor roller 2 that matches the diameter of the cable via an installation assembly. After the rotating assembly is started, it drives the conveyor roller 2 to rotate, and the cable is fed into the gap between the two rollers. Under the action of clamping force, the pressure roller 3 is passively rotated. Together, they convey the cable in a straight line. When the bend point on the cable reaches between the two rollers, the rotating assembly stops rotating and limits the rotation of the conveyor roller 2. At the same time, the driving assembly is started, and the entire installation assembly is driven to make an arc motion with its axis and the axis of the conveyor roller 2 as the center of rotation. Under the drive of the pressure roller 3, the part of the clamped cable in front of the bend point is forced to undergo plastic bending around the circumference of the conveyor roller 2 until the required angle is reached, thus completing the bend. The whole process realizes seamless switching between conveying and bend, and the structure is simple and the operation is convenient.

[0037] Example 2

[0038] like Figure 1-3 As shown, the present invention proposes a cable bending device. Compared with the first embodiment, the difference in this embodiment is that the driving component includes a turntable 4, a planetary gear 5, and a first motor 6.

[0039] There are two planetary gears 5, which are respectively installed at one end of the mounting frame 1. Each planetary gear 5 consists of a mounting frame, a sun gear, planet gears, and a ring gear. The planet gears are rotatably mounted on the mounting frame, and the sun gear and the ring gear are meshed with them. There are multiple planet gears, and the ring gear is limited by multiple planet gears and the mounting frame, so that the operation of the ring gear is relatively stable.

[0040] The first motor 6 is mounted on the side of the planetary gear 5 at one end of the mounting bracket 1. The first motor 6 is connected to the sun gear of the planetary gear 5, so that the sun gear of the planetary gear 5 drives the planetary gear to rotate and makes the gear ring rotate around the sun gear.

[0041] Turntable 4 is mounted on the outside of planetary gear 5 and connected to the mounting assembly and the gear ring of planetary gear 5.

[0042] In this embodiment, by mounting the planetary gear 5 on the mounting frame 1 and arranging its center coaxially with the center of the conveying roller 2, when the first motor 6 drives the sun gear of the planetary gear 5 to rotate, the sun gear of the planetary gear 5 drives the planetary gears to rotate and rotates the gear ring around the center of the conveying roller 2. At the same time, the gear ring of the planetary gear 5 drives the turntable 4 to rotate synchronously, so that the rotational torque of the turntable 4 is greater than the rotational torque of the first motor 6, so that the turntable 4 drives the pressure roller 3 to rotate around the conveying roller 2 through the mounting assembly, thereby making the cable bend on the conveying roller 2 more convenient.

[0043] Example 3

[0044] like Figure 4As shown, the present invention proposes a cable bending device. The difference between this embodiment and the first embodiment is that the mounting components include a mounting plate 7 and bolts 8.

[0045] The mounting plate 7 is connected to the end of the conveying roller 2 and is fitted to the turntable 4;

[0046] Bolt 8 is located on the side of mounting plate 7 and its end passes through mounting plate 7 and turntable 4 to connect with it.

[0047] In an optional embodiment, the surface of the turntable 4 is provided with mounting holes 10, and bolts 8 are located inside the mounting holes 10 and connected to the turntable 4. The number of mounting holes 10 is at least one, and the mounting holes 10 are arranged in an oblong shape, so that the position of the bolts 8 can be adjusted inside the mounting holes 10 during use, thereby causing the mounting plate 7 to drive the pressure roller 3 to adjust its position.

[0048] In an optional embodiment, a groove 11 is provided on the side of the turntable 4 and on the side of the mounting hole 10, and a slider 9 is provided on the other side of the mounting plate 7. When the mounting plate 7 and the turntable 4 are installed together, the slider 9 is accommodated in the groove 11. When the turntable 4 moves the mounting plate 7 around the conveyor roller 2 through the mounting hole 10 and the bolt 8 to bend the cable, the slider 9 and the inner wall of the groove 11 generate an interaction force, which increases the connection area between the turntable 4 and the mounting plate 7, thereby making the circumferential movement of the mounting plate 7 on the turntable 4 more stable.

[0049] In this embodiment, the mounting plate 7 is fixed to the turntable 4 by bolts 8 and connected to the bearing of the pressure roller 3. This allows the mounting plate 7 to move the pressure roller 3 while the pressure roller 3 rotates on the mounting plate 7 via the bearing. The mounting hole 10 on the turntable 4 is waist-shaped, allowing the bolts 8 to adjust the position of the mounting plate 7 inside the mounting hole 10. This, in turn, allows the mounting plate 7 to adjust the distance between the pressure roller 3 and the conveying roller 2, enabling the conveying roller 2 and the pressure roller 3 to transport cables of different sizes and perform bending operations.

[0050] Example 4

[0051] like Figure 5 As shown, the cable bending device proposed in this utility model differs from the first embodiment in that the rotating component includes a hollow shaft 12, a second motor 13, and a connecting shaft 14.

[0052] The hollow shaft 12 is located in the middle of the sun gear inside the planetary gear 5 and is rotatably connected to the mounting bracket of the planetary gear 5. In use, the hollow shaft 12 can be connected to a third motor (not shown in the figure) through a chain drive structure, so that the two planetary gears 5 can operate simultaneously.

[0053] The connecting shaft 14 is rotatably mounted in the middle of the hollow shaft 12 and extends to the outside of the planetary gear 5 at both ends. One end of the connecting shaft 14 is connected to the conveying roller 2.

[0054] The second motor 13 is located on the side of the planetary gear 5 at the other end of the mounting bracket 1 and is connected to the connecting shaft 14. In use, the second motor 13 can be a motor with an integrated reducer, which is used to reduce the driving speed of the second motor 13 and prevent the conveyor roller 2 from rotating too fast.

[0055] In this embodiment, a hollow shaft 12 is disposed inside another planetary gear 5 and connected to its sun gear. The hollow shaft 12 is rotatably connected to the mounting bracket of the planetary gear 5, so that the hollow shaft 12 supports the sun gear of the planetary gear 5. At the same time, a connecting shaft 14 is rotatably mounted inside the hollow shaft 12 and connected to the conveying roller 2 and the second motor 13, so that the second motor 13 drives the connecting shaft 14 to rotate inside the hollow shaft 12 and drives the conveying roller 2 to rotate synchronously, so that the second motor 13 drives the conveying roller 2 to perform conveying work.

[0056] In this invention, the mounting plate 7 is fixed to the turntable 4 by bolts 8 and connected to the bearing of the pressure roller 3. This allows the mounting plate 7 to move the pressure roller 3 while the pressure roller 3 rotates on the mounting plate 7 via the bearing. The mounting hole 10 on the turntable 4 is oblong, allowing the bolts 8 to adjust the position of the mounting plate 7 within the mounting hole 10. This, in turn, allows the mounting plate 7 to adjust the distance between the pressure roller 3 and the conveying roller 2, ensuring the distance between them matches the cable size. A second motor 13 drives the connecting shaft 14 to rotate inside the hollow shaft 12, causing the conveying roller 2 to rotate synchronously. One end of the cable is fed into the gap between the two rollers. Under the clamping force, the pressure roller 3 is passively... The two motors work together to transport the cable in a straight line. When the cable reaches the bend point between the two rollers, the second motor 13 stops rotating and limits the rotation of the conveyor roller 2. At the same time, the first motor 6 drives the planetary gear 5 to rotate, which in turn drives the turntable 4 to rotate. The turntable 4, through the bolt 8, drives the mounting plate 7 to make an arc motion around the axis of the conveyor roller 2. Simultaneously, the mounting plate 7 drives the pressure roller 3 to move synchronously. Under the drive of the pressure roller 3, the part of the cable in front of the bend point is forced to undergo plastic bending around the circumference of the conveyor roller 2 until the required angle is reached, thus completing the bend. The whole process achieves seamless switching between conveying and bend, with a simple structure and convenient operation.

[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
